The Washington Commanders were fined $100,000 by the National Football League for conducting excessive contact in spring drills, and will not be allowed to practice in the future.

According to a request to the Commanders, the NFL Players Association reviewed practice video on June 1 and 8 and felt those practices were in violation of the collective bargaining agreement. The practices were reviewed by the council.

The Washington general manager was told about the penalties by the league. A team does this to gain a competitive advantage, according to the letter.

The Commanders didn't want to comment.

Washington's interior line play and pass coverage during 11-on-11 drills were at a level where players were engaged in physical contests. The players went to the ground due to excessive contact between players on more than one play.

The letter stated that players were slow to recover from those crashes.

When practices became too physical and reminded players of the rules, Rivera needed to intervene.

Both Jeremy Reaves and Dyami Brown went for the ball. Reaves said he did not see Brown cutting in traffic or pulling up. After the play, Brown lingered on the ground and was escorted into the facility. Rivera stopped practice and yelled at his players to play smart and disciplined and ended the full team session early.

He claimed that Brown had a sore shoulder. The three-day mini camp was mandatory.

Rivera told the media after the collision that they need to be careful. We don't want someone to be hurt. When we talk about doing things in a specific way, there is a reason why. Guys getting hurt is something we don't want to happen.

We have to have the discipline to understand how hard they practice and how competitive they are.

There were worse accidents during practices that were not open to the media, according to one source.

All players who participate in the summer workout program will be paid for the two canceled practices.

Jack Del Rio was fined $100,000 by Rivera for comparing the events at the U.S. Capitol to rioters and looters. Rivera said Del Rio's comment about adustup distracted the team.
